Abstract

Способ и устройство для обработки потока печного газа, находящегося под давлением более 0,1 МПа (1 бар), протекающего по каналу (3). Порошкообразный агент (2), такой как порошок, содержащий щелочные реагенты, например известь, и/или абсорбенты, например активированный уголь, вводят под избыточным давлением в поток печного газа посредством форсунки (6), которая расположена по центру внутри канала. Порошкообразный агент может быть псевдоожиженным. Давление ввода порошка можно регулировать, контролируя объем ожижающего газа, выпускаемого через выходное отверстие (24).Method and device for processing the flow of furnace gas under a pressure of more than 0.1 MPa (1 bar) flowing through the channel (3). The powdered agent (2), such as powder containing alkaline reagents, such as lime, and / or absorbents, such as activated carbon, is injected under excessive pressure into the flow of furnace gas through a nozzle (6), which is located centrally inside the channel. The powdered agent may be fluidized. The injection pressure of the powder can be controlled by controlling the volume of the fluidizing gas discharged through the outlet (24).
